Current Electricity Question 11
Question 11 - 2024 (27 Jan Shift 2)
Three voltmeters, all having different internal resistances are joined as shown in figure. When some potential difference is applied across $A$ and $B$, their readings are $V _1, V _2$ and $V _3$. Choose the correct option.
(1) $V _1=V _2$
(2) $V _1 \neq V _3-V _2$
(3) $V _1+V _2>V _3$
(4) $V _1+V _2=V _3$
Show Answer
Answer: (4)
Solution:
From KVL,
$V _1+V _2-V _3=\mathbf{0} \Rightarrow V _1+V _2=V _3$
